For one, there is no native mechanism for compiling a Python program into a standalone executable package. To be fair, the original use case for Python never called for standalone redistributables.

Python modules are typically installed using a package manager called 'pip', which launches a 'setup.py' file that is made available by the developer of the package for installation purposes.

Using Python’s index operator [] on a string with a -3 will grab the 3rd character from the end of the string, in this case '<built-in function oct>'[-3] will evaluate to 'c'.
